I do my runs on a curvy road with varying inclines/declines. It starts with an underpass, makes a slight right then climbs a cable bridge across a river. From there there's a left-right switchback before the next exit. Three lanes. When I'm hustling I can usually top 4th (~190 km/h) before the end of the bridge. I've driven for 8 years on that road before seeing my first cop last week. I live a few blocks from the bridge and at night you can hear people racing on it fairly often.
